Abstract

CONJUNTO DE PERFURAÇÃO E MÉTODO DE USO DO MESMO. Um conjunto de perfuração (10) para uso em perfuração subterrânea sem valas, compreendendo: uma sapata de perfuração (20) tendo um corpo com uma porção posterior (30) e uma porção anterior (22), esta última definindo um recesso enquanto a primeira compreende brocas de perfuração (32) dispostas em uma extremidade frontal (34), lados laterais opostos, e flancos para auxiliar a sapata (20) a atuar tanto como ferramenta de perfuração de furo piloto quanto como ferramenta de alargamento; uma cabeça de perfuração (50) montada de maneira desmontável na sapata de perfuração (20) através do recesso e em comunicação com meio de orientação direcional; uma coluna de hastes de perfuração conectáveis (80), tendo uma extremidade traseira (82) e uma extremidade dianteira (84) quando conectadas, e através da qual uma solução de perfuração pode ser bombeada em direção à sapata de perfuração (20); um acoplamento (86) para ligar a extremidade dianteira (84) à referida cabeça de perfuração (50); e um conector (88) para conectar a extremidade traseira (82) a um veículo. A invenção se estende a uma sapata de perfuração (20) e um método de uso e fabricação da mesma.DRILL SET AND METHOD OF USE. A drill assembly (10) for use in trenchless underground drilling, comprising: a drill shoe (20) having a body with a rear portion (30) and a front portion (22), the latter defining a recess while the former comprises drill bits (32) disposed on a front end (34), opposite side sides, and flanks to assist the shoe (20) to act both as a pilot hole drilling tool and as a reaming tool; a drill head (50) detachably mounted to the drill shoe (20) through the recess and in communication with directional guidance means; a column of connectable drill rods (80), having a trailing end (82) and a leading end (84) when connected, and through which a drilling solution can be pumped towards the drilling shoe (20); a coupling (86) for connecting the front end (84) to said drill head (50); and a connector (88) for connecting the rear end (82) to a vehicle. The invention extends to a drilling shoe (20) and a method of using and manufacturing the same.
